That said, usually when outputting video graphics you use ITU-R.BT-601 digital sampling, so for NTSC that's 720x486 (definitely not square pixel) and for PAL it's 720x576 (again not square pixel). -- Billy Biggs [EMAIL PROTECTED] _______________________________________________ Render mailing list [EMAIL PROTECTED] http://XFree86.Org/mailman/listinfo/render
